FIG. 1 illustrates an example a system 100 for assessing a property. Inthis example, the system 100 includes a property assessment apparatus102 to inspect a space 104 in a property 106.

In some embodiments, the property 106 includes a building, such as ahouse, school, store, factory, and other structures that is used as aplace for people to live, work, do activities, store things, etc.

The space 104 in the property 106 can be of various types. In someexamples, the space 104 includes one or more conduits, such as a waterpipe, sewer pipe, gas pipe, other fluid pipe, and duct. In otherexamples, the space 104 can be any space that is not convenientlyaccessible by a person, such as a gap between structures, an attic, aceiling, a space behind a wall (e.g., drywall), and a space underflooring. The space 104 in the property 106 needs to be inspected andassessed for various purposes, such as appraisal, insurance, andmaintenance, as described herein.

The property assessment apparatus 102 operates to monitor variousconditions in the space 104, which is used to assess the space 104 inthe property 106. As described herein, the property assessment apparatus102 can be introduced into the space 104 with no or little damage to theproperty 106, and collect data in the space 104 while moving within thespace 104. An example of the property assessment apparatus 102 isfurther described with reference to FIG. 2.

In some embodiments, the property assessment apparatus 102 is operableto communicate with a property data management system 108 via a datacommunication network 110.

The property data management system 108 operates to manage datacollected using the property assessment apparatus 102. Further, theproperty data management system 108 is configured to assess the propertyfor various purposes, such as appraisal, insurance, maintenance, andremediation. In some embodiments, the property data management system108 includes one or more computing devices, which are illustrated as anexample with reference to FIG. 11.

The data communication network 110 communicates digital data between oneor more computing devices, such as among the property assessmentapparatus 102 and the property data management system 108. Examples ofthe network 110 include a local area network and a wide area network,such as the Internet. In some embodiments, the network 110 includes awireless communication system, a wired communication system, or acombination of wireless and wired communication systems. A wiredcommunication system can transmit data using electrical or opticalsignals in various possible embodiments. Wireless communication systemstypically transmit signals via electromagnetic waves, such as in theform of optical signals or radio frequency (RF) signals. A wirelesscommunication system typically includes an optical or RF transmitter fortransmitting optical or RF signals, and an optical or RF receiver forreceiving optical or RF signals. Examples of wireless communicationsystems include Wi-Fi communication devices (such as utilizing wirelessrouters or wireless access points), cellular communication devices (suchas utilizing one or more cellular base stations), and other wirelesscommunication devices.

FIG. 2 is a block diagram that illustrates an example of the propertyassessment apparatus 102. In this example, the property assessmentapparatus 102 includes a data collection device 130, an actuation device132, a communication device 134, a processing unit 136, a storage unit138, and a power supply unit 140. The devices and units can be at leastpartially received and mounted to a housing 142. In some embodiments,the property assessment apparatus 102 further includes a protective cage144.

In general, the property assessment apparatus 102 is introduced to asubject space 104 and retrieved downstream. As the property assessmentapparatus 102 traverses the subject space 104, the property assessmentapparatus 102 collects various types of data in various manners. In someembodiments, the collected data are obtained at the point that theapparatus 102 is retrieved, or after the retrieval of the apparatus 102.Alternatively, the apparatus 102 can transmit data in real time as ittraverses the subject space 104. In other embodiments, the apparatus 102is configured to move to a predetermined location in the subject space104, at which point the collected data can be obtained from theapparatus 102 by a device (e.g., an interrogation device 300 asdescribed herein) external to the subject space 104. In yet otherembodiments, the apparatus 102 can be configured to locally store thedata collected from the subject space 104 and needs not be transmittedto another computing device.

The property assessment apparatus 102 is configured to be consumable. Insome examples, the apparatus 102 is configured to be retrieved from thesubject space 104 after inspection of the subject space 104. Theapparatus 102 can be reused with or without retreatment, repair, orrestoration. In other examples, the apparatus 102 is configured to bedisposable. Once the apparatus 102 operates to collect data within thesubject space 104 and transmit the data to another computing device,such as the property data management system 108 or the interrogationdevice 300 (FIGS. 8 and 10), the apparatus 102 can remain within thesubject space 104, which can be discarded from, or together with, thesubject space 104 afterwards (e.g., when the subject space 104 iscleaned up or replaced), or reactivated for other inspections in thefuture.

In some examples, a plurality of property assessment apparatuses 102 canbe used as a group. The property assessment apparatuses 102 in a groupcan be configured for different versions or functionalities.

For example, one or more of the group of property assessment apparatuses102 (which can be referred to herein as a pilot version of propertyassessment apparatus) can be configured to assess or prepare the spacebefore other property assessment apparatus 102 having differentfunctionalities, such as a data collection version of propertyassessment apparatus 102, is introduced into the space. The pilotversion of apparatuses can be configured as a set of objects indifferent sizes, at least some of which can self-destruct withoutdamaging the space. The speed of the objects of different sizes candetermine the size of the apparatus that will be able to traverse thespace. By way of example, if the apparatus can get stuck in the spaceand/or needs to e dissolve before reaching the end of the space, theapparatus can be configured to move slowly. In some example, the pilotversion of apparatus can include a guide line (e.g., a thin cord, wire,or similar type of line) that is tied to an end of the apparatus, sothat the apparatus can be pulled through. In other example, the pilotversion of apparatus can affix itself to the interior of the space andprovide a mount point for the apparatus.

Other versions of apparatuses 102 are also possible. In one example, apower supply version of the apparatus can be provided, which isconfigured to deliver a battery to another apparatus that is mounted inthe space or is moving in the space. In another example, a samplecollection version of the apparatus can be provided, which is configuredto collect samples from another apparatus that is mounted in the spaceor is moving in the space, and deliver them out from the space.

Referring still to FIG. 2, the data collection device 130 operates tocollect data from the subject space 104 of the property 106 beinginspected. The data collected by the apparatus 102 can be of varioustypes. Examples of such collected data include measurements (e.g.,temperature, carbon monoxide content, etc.), signals, digital images(including videos), and samples (e.g., physical, chemical, andbiological samples) of the contents of the subject space. Examples ofthe data collection device 130 are further described with reference toFIG. 3.

The actuation device 132 operates to actuate the apparatus 102 so thatthe apparatus 102 travels within the subject space 104. The actuationdevice 132 can configured to be of various types. Examples of theactuation device 132 are further described with reference to FIG. 4.

The communication device 134 operates to enable the apparatus 102 tocommunicate with other computing devices, such as the property datamanagement system 108, the interrogation device 300, and any otherdevices to transfer data therebetween.

In some embodiments, the communication device 134 includes an antenna146 configured to transmit at a predetermined frequency. The antenna 146can be used to wirelessly (e.g., inductively) power the units anddevices in the apparatus 102. As illustrated in FIG. 8, the apparatus102 is arranged close to, or abutted to, an inner surface of a wall 304of the subject space 104, and an interrogation device 300, which islocated exterior of the subject space 104, can be used to wirelesslytransfer power to the apparatus 102 through the wall 304 of the subjectspace 104. Such wireless power transfer can use time-varying electric,magnetic, or electromagnetic fields 302. For example, power can betransferred by magnetic fields using inductive coupling between theapparatus 102 and the interrogation device 300. In other examples, powercan be transferred by electric fields using capacitive coupling betweenthe apparatus 102 and the interrogation device 300. In yet otherexamples, far-field techniques can be used, such as usingelectromagnetic radiation between the apparatus 102 and theinterrogation device 300.

In some embodiments, the communication device 134 includes a speaker148. The speaker 148 operates to generate audio signals that are used tolocate the apparatus 102 within the subject space 104. Theidentification of apparatus location can help retrieving the apparatus102 from the subject space 104 or verifying the movement of theapparatus 102 within the subject space 104. In addition, the speaker 148can generate different audio signals (which are adjusted in variousmanners (e.g., sound types and/or volumes)) so that such different audiosignals are used to deliver different pieces of information, such asdifferent conditions detected within the subject space 104.

The audio signals generated by the speaker 148 are configured totransmit through the walls (e.g., metal walls) of the subject space 104.In some embodiments, the audio signals are encoded to sonically transmitlarge amount of information, which can be detected by an externalcomputing device, such as the interrogation device 300 or the propertydata management system 108. For example, frequency, timing, and/oramplitude changes can be used to encode the information, like FM or AMradio transmission or ultrasonic data transmission. In someapplications, the apparatus 102 can generate s sound signal within thesubject space, which is transmitted through the wall of the subjectspace. A user can either directly hear the sound signal or use anexternal device to detect the sound signal. The external device can beused to deliver a quality version of the sound signal to the user. Inaddition, the user can use the external device to control the propertyassessment apparatus 102 within the subject space 104, such as tocontrol the apparatus 102 to find a particular condition within thesubject space 104 and transmit the finding back to the external device.

The processing unit 136 operates to control other devices and componentsof the apparatus 102, such as the data collection device 130, theactuation device 132, and the communication device 134. In someembodiments, the processing unit 136 includes an integrated circuit (IC)configured to assess and/or store data (e.g., the data collected fromthe subject space 104). The processing unit 136 can be configured forsimple evaluation for initial assessment purposes, such as adetermination of existence of a particular condition (e.g., “is aparticular condition present in the subject space being monitored?”).The processing unit 136 can be configured for further, sophisticatingassessment of the subject space. In some embodiments, the processingunit 135 is configured to evaluate the collected data, such asprocessing and analyzing of the data and assessing the property 106 invarious manners. The processing unit 136 can be implemented in a wayknown in the art, including, for example, a processor, a decoder, and anencoder.

The storage unit 138 includes one or more memories configured to storedata, such as the data collected from the subject space and other datausable to evaluate the collected data. The storage unit 138 can be ofvarious types, including volatile and nonvolatile, removable andnon-removable, and/or persistent media. In some embodiments, the storageunit 138 is an erasable programmable read only memory (EPROM).

The housing 142, which at least partially receives andmounts the devices, units, elements, and components of the apparatus102, can be configured to enable the apparatus 102 to float within asubject space 104. For example, the housing 142 can be configured to beneutrally buoyant.

The housing 142 can be configured to be impermeable to fluid in asubject space 104 and/or corrosion-resistant with the fluid in thesubject space 104. The housing 142 can be made of various materials,such as foam, gel, plastic, rubber, metal, and any other suitablematerials for buoyancy. In some examples, the housing 142 includes acontainer (e.g., chamber or bag) that can contain a lifting gas tocreate buoyancy. The container of lifting gas 133 is mounted to thehousing 142 of the apparatus 102 (e.g., to a mounting device 206 in FIG.5), or received within the housing 142 of the apparatus 102.Alternatively, the container of lifting gas can be a separate unit fromthe apparatus 102. Examples of the lifting gas include helium, hydrogen,heated air, steam, ammonia, methane, neon, nitrogen, vacuum, plasma, andany combination thereof. By way of example, the housing 142 includes aspace for receiving a balloon that can be inflated with a lifting gas.

The housing 142 can be configured in various shapes. In someembodiments, the housing 142 is shaped to avoid being caught or stuck bystructures in the subject space 104.

The propellers 202 are spaced apart from each other toprovide stability to the apparatus 102 in operation. In someembodiments, at least one of the propellers is arranged to face upwards(e.g., located on the top of the apparatus 102) so that the apparatus102 is driven as a drone. In other embodiments, at least one of thepropellers 202 is arranged to enable the apparatus 102 to float like ablimp. In yet other embodiments, the propellers 202 are arranged toenable the apparatus 102 multidirectional movements.

The propellers 202 can be of various configurations. The propellers 202are configured to be unidirectional or bidirectional. In someembodiments, six propellers 202 are symmetrically positioned around thehousing 412 of the apparatus 102. Other numbers of propellers 202 can besymmetrically provided on the housing 412. In some embodiments, thepropellers 202 are mounted to the housing 412 to be breakable (i.e.,breakway mount).

FIG. 8 schematically illustrates that the property assessment apparatus102 communicates with an interrogation device 300 external to a subjectspace 104. In some embodiments where a wall 304 of the subject space 104is made of metallic material, the apparatus 102 includes a magneticelement, such as a magnet, solenoid (which can be powered by a batter inthe apparatus), or ferromagnetic material, which enables the apparatus102 to adhere to the wall 304 of the subject space 104. When theadhesion occurs, the metallic wall 304 can enable transmission of databetween the apparatus 102 and the interrogation device 300 through thewall 304. Alternatively, the apparatus 102 includes a suction devicehaving conductive bits. The suction device can enable the apparatus 102to adhere to the inner wall of the subject space 104 while theconductive bits are used for data transmission between the apparatus 102and the interrogation device 300 through the wall 304.

In other embodiments, the interrogation device 300 are provided externalto the subject space 104 to attract the apparatus 102 inside the subjectspace 104 by sending homing signals to the apparatus 102 so that theapparatus 102 adheres to the wall 304 of the subject space 104. Theadhesion can happen due to a magnetic or electromagnetic field generatedbetween the apparatus 102 and the interrogation device 300 that includesa corresponding magnetic element, such as a magnet, solenoid, orferromagnetic material.

FIG. 9 is a flowchart of an example method 330 for assessing a propertyusing the property assessment system 100. In this example, the method330 includes operations 332, 334, 336, 338, 340, and 342. In otherexamples, the method 330 includes one or more other operations inaddition to all or some of the operations in this example. The method330 is described with reference also to FIG. 10, which illustrates thatthe property assessment apparatus 102 moves through an example subjectspace 104.

The method 330 can begin at operation 332 in which the propertyassessment apparatus 102 is introduced into a subject space 104 in aproperty 106 to be inspected. As described herein, the subject space 104can be of various types, some examples of which include a conduit, suchas a water pipe, sewer pipe, gas pipe, other fluid pipe, and duct. Sucha conduit can be either fully enclosed or partially open such as aculvert (e.g., open at inlet(s) and outlet(s)). The subject space 104can further include any space that is not conveniently accessible by aperson, such as a gap between structures, an attic, a ceiling, a spacebehind a wall (e.g., drywall), and a space under flooring. The property106 can be of various types, such as residential properties orcommercial properties.

In some embodiments, the property assessment apparatus 102 is launchedat an existing opening or hole of the subject space 104, such as a ventor other opening of a conduit. In other embodiments, a small hole can bemade to the subject space 104, which is sized enough to receive theproperty assessment apparatus 102 but not destructive to the property106 (or minimum destruction). In some embodiments, there is no need ofturning off fluid through the subject space.

At operation 334, the property assessment apparatus 102 operates to movewithin the subject space 104 and collect data from the subject space104. As described above, some embodiments of the apparatus 102 areconfigured to be neutrally buoyant in the subject space 104 and movewith flow inside the subject space. Other embodiments of the apparatus102 are configured to float and move along flow inside the subjectspace. Yet other embodiments of the apparatus 102 are powered by a smallactuator, such as by operating one or more propellers, by releasingpropellant, by a small turbine, or by any battery-powered means.

As described herein, the apparatus 102 can be introduced into fluid flow(e.g., liquids or gases) in the subject space 104 regardless of whetherthe subject space 104 is configured as a conduit. Further, when theapparatus 102 is self-propelled, the apparatus 102 does not requirefluid flow for placement or retrieval. For example, the apparatus 102,if configured to be neutrally buoyant slow-moving, neither gets stuckwithin the subject space 104 nor have parts (e.g., propeller blades)damaged in operation within the subject space 104.

In some embodiments, as described herein, the apparatus 102 areconfigured to travel to a predetermined location within the subjectspace 104. For example, the apparatus 102 includes a magnetic element,which is attracted to a corresponding magnetic element of a deviceexternal to the subject space 104. Such a magnetic attraction can enablethe apparatus 102 to a particular location within the subject spacewhere the external device is arranged outside the subject space.Alternatively, as described herein, inductive power can be used toattract the apparatus 102 to a location near the external device. Forexample, the apparatus 102 includes an antenna so that the apparatus 102is powered by the external device through induction.

At operation 336, the property assessment apparatus 102 can be retrievedfrom the subject space 104. In some embodiments, the apparatus 102 istaken out from a different location than the location where theapparatus 102 is inserted into the subject space 104. In otherembodiments, the apparatus 102 is retrieved from the same location wherethe apparatus 102 is inserted.

Alternatively, the apparatus 102 can remain with the subject space 104once it finishes collecting data as programmed. The remaining apparatuscan be retrieved later, reused for other inspections, or at leastpartially deflated (or dissolved) within the subject space 104.

At operation 338, the data collected by the property assessmentapparatus 102 are obtained from the apparatus 102. Depending on the typeof collected data, the method for obtaining the data may vary. Forexample, measurements, signals, images, or videos can be transmitted toa computing device, such as the interrogation device 300 and theproperty data management system 108, and saved therein in digitalformats. Samples or particles can be physically gathered and deliveredto a laboratory (such as a lab operating the property data managementsystem 108) for further analysis.

In other embodiments, the data can be obtained before the apparatus 102is retrieved from the subject space 104 (operation 336) or while theapparatus 102 remains within the subject space 104. For example, whilethe apparatus 102 is in the middle of a conduit, the data can betransmitted to an external computing device via a short-range wirelesscommunications or to a remote computing device (e.g., the property datamanagement system 108) via a long-range wireless communications.

At operation 340, the obtained data is analyzed for assessing thesubject space 104. In some embodiments, the obtained data is used toevaluate the structure of the subject space 104 and the contentscontained therein. For example, the data can be used to determinechemical composition of the structure of the subject space 104 (e.g.,conduit lining chemical composition). Further, the data is used toidentify a fluid contained in the subject space 104, such as quality andcomposition of expected fluid ingredients and/or contaminants (e.g.,heavy metals, excessive volatile components, undesirable water ormoisture, ice, mineral build-up, etc.). In addition, the data can beused to examine structural integrity of the subject space, such as byvisual or sonic interrogation of the subject space. The data can furtherbe used to locate any other devices or structures that are presentwithin the subject space 104. Such other devices or structures may beundesirable within the subject space 104, which may have been leftbehind or planted maliciously.

At operation 342, the assessment of the subject space 104 is used toassess the property 106 including the subject space 104 for variouspurposes, such as appraisal, insurance, and maintenance, of theproperty. The followings are some example applications of the dataassessment.

In some examples, the data obtained and assessed from the subject space104 using the property assessment apparatus 102 can be used to evaluatethe property 106 for appraisal or maintenance. For example, the intakeand outflow of fluids (e.g., water or gas) through the subject space 104can be assessed based on the data obtained at the operation 340 and usedto evaluate the integrity of property structure for appraisal ormaintenance. The obtained data also can be used to assess the intake andoutflow of fluids through the subject space 104 and then identifypotential features or hazards in the property for appraisal ormaintenance.

In some examples, the data obtained and assessed from the subject space104 using the property assessment apparatus 102 can be used to assesspersonal or commercial properties, such as industrial sites and publicworks (e.g., water pipes, conduits, sewer lines, natural gas lines,refinery conduits, pipes on ships, intake and outflow piping onaircraft).

In some examples, the data obtained and assessed from the subject space104 using the property assessment apparatus 102 can be used for targetedremediation. Examples of targeted remediation include chemicallyneutralizing an issue, plugging leakage, deactivating intruder devices(e.g., cutting through an intruder circuit, applying shock to anintruder device, and collecting an intruder device), warming up icyarea, boring through a blockage, performing a small explosion near ablockage, dropping insect or rodent repellent, etc.).

In some examples, the data obtained and assessed from the subject space104 using the property assessment apparatus 102 can be used for variousinsurance applications.

The property assessment apparatus 102 and the method of operating thesame enable more detailed assessment than typical property assessmentpractices, due to relative low cost and low invasiveness of theapparatus 102 and the method of operating the same. Typical propertyassessment practices involve creating large holes or removal of facades.In contrast, the method of operating the apparatus 102 according to thepresent disclosure does not require creating new holes or only requiressmall holes for introducing the apparatus 102. The more detailedassessment by using the apparatus 102 and the method of the presentdisclosure allows more favorable pricing of insurance for customers dueto the risk mitigation allowed by detailed inspection. Further, the moredetailed assessment of the present disclosure can identify propertiesthat would be unfavorable to insure, such as hazards which are notobvious without the detailed inspection.

The property assessment apparatus 102 and the method of operating thesame can be used to identify code violations associated with theproperty 106 inspected. With such identification, insurance can bepredicated on fixing the violations, or the premium can increase whenthe violations are not fixed.

The property assessment apparatus 102 and the method of operating thesame can turn risky properties to be insurable. For example, propertiesin a flood prone area can be insurable if tenants or homeowners agree tospecific periodic inspections using the apparatus 102. The pricing canbe determined according to findings of initial inspection and predicatedon continued periodic inspections coming back clean. For example,flooding can be expected up to certain point in a property. If floodingexceeds the point, the property can henceforth be uninsurable or getdifferent pricing.

Information from detailed assessments of a number of properties usingthe method of the present disclosure can be pooled to calculate risk onanother property. For example, the risk on properties at an elevationmay be similar to nearby properties at a similar elevation which haveexperienced flooding. The risk can increase on a property sharing awooden wall with another uninsurable property due to fire hazards.Properties having certain level of mildew or wood rot, in combinationwith certain level of external flood hazard, are suggestive of futurehazards to properties with similar conditions. These situations can besuggestive of untestable factors such as the tenants or homeowners'willingness to protect properties.

The property assessment system of the present disclosure enablescollecting standardized data elements which can be meaningfully pooledand analyzed. Images captured during data collection by the apparatus102 can be tagged with appropriate names and other information to thisend. Collected data can be maintained about suspected hazards andconfirmed hazards so that modeling and analyzing (e.g., using machinelearning technology) can be performed.

In some embodiments, a risk score can be created as a product, whichquantifies various undesirable conditions (e.g., hazards) as collectedby the property assessment apparatus 102. For example, the risk ofnegative outcome can be calculated as a score based on presence of knownhazards. By way of example, a risk score increases if there are beamsinstalled incorrectly, because such incorrectly installed beams maycause building collapse if there is ground movement.

In some embodiments, the risk scores that are calculated based on thedata collected and analyzed using the property assessment system of thepresent disclosure can be combined with traditionally collected dataelements.

In some embodiments, a risk score can be created as a product, whichquantifies presence of undesirable conditions (e.g., hazards) based oninconclusive data collected by the property assessment apparatus 102.Such a risk score can represent a risk of true presence of undesirableconditions, such as a risk of previous severe flood based on presence ofvarious conditions (e.g., mildew type and prevalence, mold type andprevalence, wood rot type and prevalence, photographs of blotchy area,etc.).

The property assessment system of the present disclosure can be used forinsurance of industrial properties. The pricing can be predicated onperiodic inspection of infrastructure by the property assessmentapparatus 102, which provides a low cost, efficient, and more detailedalternative to or supplement of on-site inspections by humans.

The property assessment system of the present disclosure can be used toevaluate various risks for insurance purposes. In an example of floodrisk, the insurer the provides insurance for flood risk areas canspecify that the property assessment apparatus 102 be introduced tocertain areas on a regular basis and sent back to a lab for analysis.The lab can examine the collected data (e.g., measurements and samples)and generate a report. The report can include various information, suchas current conditions (e.g., mold, mildew, wood rot, and moisture) inthe inspected property, and a past property damage history (e.g.,flooding) assessed based on the current conditions. The lab can furtherinspect the apparatus to ensure that the apparatus has not been tamperedby the user.

Similarly to the example of flood risk above, in an example of firehazards, the property assessment apparatus 102 can be used to identifywiring problems, such as outdated wiring, uninsulated wiring, inadequategauge, overloaded wiring, and any other incorrect wiring.

Similarly to the example of flood risk above, in an example of hazardousmaterials, the property assessment apparatus 102 can be used toidentify, for example, chemicals, spills, asbestos, and lead (e.g.,solder in pipes). As described herein, these materials can be obtainedby capturing images and/or collecting samples. In some example, thesamples can be collected only after materials are allegedly identifiedby the images.

Similarly to the example of flood risk above, in an example ofearthquake safety, the property assessment apparatus 102 can be used toidentify or confirm structural soundness of architectural elements thatare not easily accessible.

In some examples, the data obtained and assessed from the subject space104 using the property assessment apparatus 102 can be used forappraisal purposes.

The property assessment apparatus 102 and the method of operating thesame enable more detailed assessment than typical property assessmentpractices, due to relative low cost and low invasiveness of theapparatus 102 and the method of operating the same. Typical propertyassessment practices involve creating large holes or removal of facades.In contrast, the method of operating the apparatus 102 according to thepresent disclosure does not require creating new holes or only requiressmall holes for introducing the apparatus 102. The more detailedassessment by using the apparatus 102 and the method of the presentdisclosure allows more accurate estimates of property value. Someundiagnosed issues can include past flooding, fire hazards, andstructural issues (e.g., beams incorrectly placed behind walls, inexpertrenovations, small fires that damaged unit elements, animal damages,etc.). Some finds from the apparatus 102 may lead to lower appraisedvalue, or requirement of remediation of issues prior to issuing amortgage.

The property assessment system of the present disclosure may provide alower cost alternative to onsite visits by humans. For example, in thecase of high values properties, the property assessment system of thepresent disclosure can provide supplementary information not generallyavailable to onsite human inspectors.

Some appraisals can include inspection of properties to find mold,mildew, wood rot, and moisture using the apparatus 102 and evaluate themto look for past flooding of the properties, either flooding from theexterior or interior leaks (e.g., pipe problems, roof leaks, etc.).

The property assessment system of the present disclosure can be used toidentify code violations associated with the property 106 inspected.Such identification of code violations can affect appraised value ifthey need to be fixed or pose risks.

The property assessment system of the present disclosure can be used toevaluate various risks for appraisal purposes. In an example of firehazards, the property assessment apparatus 102 can be used to identifywiring problems, such as outdated wiring, uninsulated wiring, inadequategauge, overloaded wiring, and any other incorrect wiring. The apparatus102 can further be used to detect evidence of past fires. In an exampleof hazardous materials, the property assessment apparatus 102 can beused to identify, for example, chemicals, spills, asbestos, and lead(e.g., solder in pipes). As described herein, these materials can beobtained by capturing images and/or collecting samples. In some example,the samples can be collected only after materials are allegedlyidentified by the images. In an example of earthquake safety, theproperty assessment apparatus 102 can be used to identify or confirmstructural soundness of architectural elements that are not easilyaccessible.

According to the present disclosure, in some embodiments, the propertyassessment apparatus 102 can be configured to be used to temporarilyblock or plug a hole in the subject space (e.g., a conduit). This canhelp stopping flow downstream in the conduit so that the downstream ofthe conduit can be inspected. Further, the apparatus 102 can function asan emergency water stopper or stoppage buster. The apparatus 102 can beretrieved after use.

In some embodiments, the apparatus can carry a clog-busting product orclog remover and release it when the apparatus reaches a cloggedlocation in the conduit.

In some embodiments, the property assessment apparatus 102 can be leftin the subject space after use. The apparatus 102 can be configured toautomatically deflate (self-deflated) within the subject space. By wayof example, where the housing 142 of the apparatus 102 is configured as,or includes, an inflatable balloon, the balloon can be exploded (e.g.,with a needle contained in the apparatus 102) or deflated itself asprogrammed. An alternative method for deflating the apparatus 102 ismaking the housing of the apparatus (or the inflatable part of thehousing) with a slowly dissolving material. Such explosion or deflationcan avoid the apparatus causing clogs or obstruction within the subjectspace.

The apparatus 102 being used to create an intentional blockage which isremoved later can automatically unblock eventually if a normal use ofthe apparatus does not work.

The apparatus 102 that is used in an aqueous environment can be made atleast partially of materials that slowly dissolve in water. Similarly,the apparatus 102 that is used in an oil based environment can be madeat least partially of materials that slowly dissolve in oil. Similarly,the apparatus 102 that is used in air can be made at least partially ofmaterials that slowly disintegrate when exposed to oxygen or other gasesin air.

The thickness of materials used to make the apparatus can be used tocontrol how long the apparatus works. For example, the thickness of theinflatable portion of the apparatus can be used to control how long thatpart is inflated in the subject space. In some examples, there can be asmall portion of the inflatable part that changes thickness while therest is a standard thickness greater than the part used to control theinflation.

Although the operation of the property assessment apparatus 102 isprimarily described where the apparatus 102 is used with the conduitsystem as illustrated in FIG. 10, it is understood that the apparatus102 can be used with any other spaces, one example of which is an attic.By way of example, the property assessment apparatus 102 is launchedinto an attic to take pictures, measure the internal temperature, andperform other data collections inside the attic. Such collected data canbe used to determine the condition within the attic, determine whether afan needs to be installed in the attic, determine what kind oftemperature remediation is needed in the attic, assess insulation orlack thereof, and/or determine where ducts or pipelines need to beplaced in the attic.

In some embodiments, the subject space 104 is constructed to incorporatea track for the property assessment apparatus 102. In an example of aconduit as the subject space, the conduit can be configured andinstalled to have a track incorporated, and the apparatus moves on thetrack along the conduit.

Wirelesscommunication between input devices and interface 438 is possible aswell, and includes infrared, BLUETOOTH® wireless technology,802.11a/b/g/n, cellular, or other radio frequency communication systemsin some possible embodiments.

In this example embodiment, a touch sensitive display device 440 is alsoconnected to the system bus 406 via an interface, such as a videoadapter 442. The touch sensitive display device 440 includes touchsensors for receiving input from a user when the user touches thedisplay. Such sensors can be capacitive sensors, pressure sensors, orother touch sensors. The sensors not only detect contact with thedisplay, but also the location of the contact and movement of thecontact over time. For example, a user can move a finger or stylusacross the screen to provide written inputs. The written inputs areevaluated and, in some embodiments, converted into text inputs.

In addition to the display device 440, the computing device 400 caninclude various other peripheral devices (not shown), such as speakersor a printer.

The computing device 400 further includes a communication device 446configured to establish communication across the network. In someembodiments, when used in a local area networking environment or a widearea networking environment (such as the Internet), the computing device400 is typically connected to the network through a network interface,such as a wireless network interface 450. Other possible embodiments useother wired and/or wireless communication devices. For example, someembodiments of the computing device 400 include an Ethernet networkinterface, or a modem for communicating across the network. In yet otherembodiments, the communication device 446 is capable of short-rangewireless communication. Short-range wireless communication is one-way ortwo-way short-range to medium-range wireless communication. Short-rangewireless communication can be established according to varioustechnologies and protocols. Examples of short-range wirelesscommunication include a radio frequency identification (RFID), a nearfield communication (NFC), a Bluetooth technology, and a Wi-Fitechnology.

The computing device 400 typically includes at least some form ofcomputer-readable media. Computer readable media includes any availablemedia that can be accessed by the computing device 400. By way ofexample, computer-readable media include computer readable storage mediaand computer readable communication media.

Network-basedsystems utilize service provider's network infrastructure, such as celltower triangulation. Handset-based systems typically use the GlobalPositioning System (GPS). Wi-Fi positioning systems can be used when GPSis inadequate due to various causes including multipath and signalblockage indoors. Hybrid positioning systems use a combination ofnetwork-based and handset-based technologies for location determination,such as Assisted GPS.

In some examples, the computing device 400 is configured to operate as,or work with, a transaction instrument, in which payment information istransmitted via the communication device. As described herein, thecomputing device 400 as such a transaction instrument can be implementedin the property assessment apparatus 102, the property data managementsystem 108, and other computing devices associated with the apparatus102 and/or the system 108.

In the present disclosure, such payment can include payment forinspection, remediation, or assessment of the space or the property. Thepayments can be micropayments. The payments can be assessed by thecomputing device 400 per service performed (e.g., each time a clog isremediated, or an image captured, or a sample collected), or may bebatched per a series of services. The transaction instrument can beconfigured to work with various types of payment instruments, such ascredit cards, debit cards, digital currency, or other suitable paymentinstruments. The computing device 400 can allow for different types ofservices to be paid for different transaction instruments or paymenttypes, such as Automated Clearing House (ACH), wires, etc. In someexamples, the computing device 400 is configured as a digital walletthat contains transaction instruments.

As such, a property assessment device of the present disclosure is usedto better understand what is happening in a space that is not easilyaccessible, such as conduits for fluids (e.g., air ducts and pipes forliquids). The property assessment device is configured and used toassess such a space and the contents therein, which may revealinformation that affects the value of a property that contains thespace. The assessment by the property assessment device can also be usedto provide information that reveals the maintenance requirements of thespace and its contents, and remediation needs upstream.

As described herein, the space can be assessed by the propertyassessment device that is introduced at a first location (e.g.,upstream) of the space and extracted at a second location (e.g.,downstream) of the space. The property assessment device is “ingestible”by the property and moves in the space for assessment. The propertyassessment device can move in the space in various manners. In someembodiments, the property assessment device is configured to include anair balloon that enables the property assessment device to float ordrift through the space. In other embodiments, the property assessmentdevice is configured to be self-propelled.

In some embodiments, the information collected by the propertyassessment device is transferred to an external computing device, eitherwirelessly or in a wired connection, once the property assessment deviceis collected at the second location of the space. In other embodiments,the property assessment device can operate transmit information in realtime as it traverses the space. In yet other embodiments, an externaldevice can be used to collect information from the property assessmentdevice at a predetermined or random location where the propertyassessment device is positioned in the course of movement.

The various examples and teachings described above are provided by wayof illustration only and should not be construed to limit the scope ofthe present disclosure. Those skilled in the art will readily recognizevarious modifications and changes that may be made without following theexamples and applications illustrated and described herein, and withoutdeparting from the true spirit and scope of the present disclosure.
